Diseases Treated

People with many kinds of cancer receive radiation therapy to cure, stop, or slow their disease; to reduce the risk that it will come back; or to relieve symptoms caused by tumors. Radiation therapy is used to treat the primary site of some kinds of cancer, such as breast, colon, lung, and prostate cancers. It’s also used to treat metastases—areas where cancer has spread—including to the bones, brain, and other organs.
